Due to the nature of how LEDs work and the minimal power usage some vehicles refuse to accept the trailer is actually connected - in these cases the use of this plug in line adaptor is required.
It consists of a plastic bodied adaptor with a 13 pin plug at one end and a 13 pin socket at the other making it a true plug and play solution that does not require any installation or tools and can be easily transferred between vehicles.
